有没有办法用代码编写Eclipse文件搜索(Ctrl + H)？

            // 获取所有的Java项目

            // 创建一个搜索范围，包含所有的Java项目
            IJavaSearchScope searchScope = SearchEngine.createJavaSearchScope(javaProjects, IJavaSearchScope.SOURCES);

                }
            };
            // 执行搜索
            searchEngine.search(searchPattern, new SearchParticipant[] { SearchEngine.getDefaultSearchParticipant() },
                    searchScope, searchRequestor, new NullProgressMonitor());
        } catch (CoreException e) {
            e.printStackTrace();
        }
    }
